Abstract

Soil-borne barley viruses were investigated in 42 regions during 1999-2003, in Korea. BaYMV, BaMMV and SbWMV symptoms were found in 37 regions. Crops resistance to mosaic viruses were investigated by growing them on 10 regions infected with soil-borne viruses. It was found that 10 unhulled barley, 6-beer bar]ey, 16 rye and 2 wheat species showed resistance to virus. Most of 15 Japanese cultivars showed infection symptoms but many of them showed relatively higher resistance in Ikasan, Youngkwang and Yesan areas region. Mixed virus infection was investigated and it was found that inter-regional species except in 10 areas, were mix infected with BaYMV and BaMMV. But in Youngkwang area all of crop species except Secheon-6 were infected only with BaYMV. Japanese cultivars were mixed infected with BaMMV and BaYMV except at Yesan that were infected only with BaYMV.

1999년부터 2001년까지 전국42개 지역에서 토양전염성 맥류바이러스를 조사한 결과 강원도 영월, 전라북도 무주, 충청남도 공주, 보령, 서천 포장을 제외한 37개 포장에서 BaYMV, BaMMV 및 SbWMV가 발생하고 있었다. 또한 토양전염성 맥류바이러스 상습 발병지 10개 장소에 겉보리 10품종, 쌀보리 16품종, 맥주보리 6품종, 밀 2품종을 파종하고 저항성 조사를 실시한 결과 겉보리는 조강보리, 쌀보리는 내한쌀보리 및 논산과1-6품종이 비교적 여러지역에서 저항성 높은 품종으로 나타났다. 그리고 일본에서 분양 받은 15품종도 대부분이병성으로 나타났으나 특이하게 익산, 영광 및 예산지역에서 저항성 품종이 많았다. 지역간 품종에 따른 바이러스 혼합 감염을 조사한 결과 조사 10개 지역 모두 BaYMV, 및 BaMMV가 혼합 감염되어 있었고, BbWMV는 예산, 진주, 나주 및 익산지역에 혼합감염되어 있었다. 그러나 영광지역에서는 사천6호 품종을 제외하곤 BaYMV만이 발생하였다. 일본 분양 품종은 예산에서만 BaYMV가 감염되었고 나머지 지역에서 모두 BaMMV 및 BaYMV에 혼합 감염되 어 있었다.
